The WITH that I am thinking about, lets you define and reuse queries which are executed once. For example:
WITH MySummary AS (*SELECT b.dept_name, Sum(Salary) AS total_sal FROM emp a join dept b on (a.dept_id = b.dept_id)
GROUP BY b.dept_name*) SELECT dept_name, total_sal //FROM MySummary WHERE total_sal > ( SELECT
SUM(total_sal) * 1/12 FROM MySummary) ORDER BY total_sal
You can introduce multiple "aliases" and use them within any subsequent queries.
WITH alias1 as (...) alias2 as (...) alias3 as (...)
SELECT ....
